The rise in fuel prices, especially diesel, has pushed up fish prices but has had little effect on vegetable prices.
Fish shipments at the Kasimedu harbor have decreased, resulting in a price hike. Many boats, including the majority of the trawlers, have stayed anchored in the harbor, according to a vendor at the harbor.
He said that the price of fish was higher than it was on March 20.
Another vendor claimed that the formation of low pressure in the Andaman Islands was another reason for many boats not putting out to sea over the last week, resulting in a price hike.
When the annual fishing ban goes into effect in a fortnight, the supply will drop much more, he warned.
Most vegetables at the Koyambedu are still affordable to the average people, according to PG M Sukumar, treasurer of the wholesale dealers' association.
"Most vegetables were sold within Rs 15-Rs 30 per kilogram range," he explained. With the exception of beans, drumsticks, chili, and green peas, the majority of the produce remained affordable.
More than 8,000 tons of vegetables are delivered daily to the market by more than 500 trucks from various regions of Tennessee, as well as Karnataka, Andhra Pradesh, and Maharashtra.
The previous year's abundant rain resulted in a good vegetable harvest in the last three months, which helped keep prices in check.
